Systemic lupus erythematosus (SLE) is a life-threatening multisystem inflammatory condition that may affect almost any part of the eye. We provide an update for the practicing ophthalmologist comprising a systematic review of the recent literature presented in the context of current knowledge of the pathogenesis, diagnosis, and treatment of this condition. We review recent advances in the understanding of the influence of genetic and environmental factors on the development of SLE. Recent changes in the diagnostic criteria for SLE are considered. We assess the potential for novel molecular biomarkers to find a clinical application in disease diagnosis and stratification and in the development of therapeutic agents. We discuss limited forms of SLE and their differentiation from other collagen vascular disorders and review recent evidence underlying the use of established and novel therapeutics in this condition, including specific implications regarding monitoring for ocular toxicity associated with antimalarials.

LessonFungi of the genus Phoma are common plant pathogens and saprophytes and are rarely pathogenic to animals.

Uveitis patients' understanding of their condition is poor. This has relevance for adherence to treatment, follow-up clinic attendance, and eventual outcomes in these patients.

Background/Aims  Cytomegalovirus (CMV) retinitis is one of the most common opportunistic ocular infections and has traditionally been associated with immunocompromised individuals. We present a case of CMV retinitis following 3 months of treatment with tofacitinib in conjunction with methotrexate (MTX) for rheumatoid arthritis (RA) in an elderly lady with no other co-morbidities. Methods  The case is presented below. Results  69-year-old lady with long standing seronegative, anti-cyclic citrullinated peptide negative, erosive RA since 2016. She was intolerant of sulphasalazine, leflunamide, methotrexate and etanercept. Hydroxychloroquine was avoided due to idiopathic cystoid macular oedema in the right eye with a baseline visual acuity of 6/18. Baseline fundus fluorescein angiogram (FFA) was negative for any vascular, inflammatory or occlusive disease. She was escalated to tofacitinib in August 2019. Approximately 3 months later, she noticed significantly reduced vision in her right eye from 6/18 down to 6/60. She had an FFA and Indocyanine Green Angiography, which showed quite extensive retinal ischaemia and vasculitis. Her bloods revealed a raised serum ACE and a T-spot test from 2018 was reactive followed by a repeat in 2019 which was equivocal. Tofacitinib was discontinued. She was commenced on rifampicin and isoniazid as 3 months prophylaxis for latent tuberculosis (LTBI). Additionally, she was started on oral prednisolone 60mg daily for presumed sarcoid related retinal vasculitis. She failed to improve despite a week’s treatment and subsequently had a vitreous aspirate which was strongly positive for CMV PCR. Her CMV viral load was 267copies/ml. The aspirate was negative for other infectious agents. She was commenced on valganciclovir for CMV retinitis. Unfortunately, her vision remained unchanged despite the viral load becoming undetectable a few weeks later. Despite having LTBI, there was no reactivation of this with her immunosuppressive therapy. Conclusion  CMV retinitis is usually associated with immunocompromised individuals and is rarely encountered related to tofacitinib therapy for rheumatoid arthritis. Tofacitinib suppresses T cell function by inhibiting STAT signalling pathways, modulating T cell activation and cytokine production. Our case highlights the preferential development of CMV retinitis over active TB in the presence of LTBI, which is a recognised risk with the use of JAK kinase inhibitors. TB risk has been associated with genetic mutations in IL-12, IFN-γ and STAT1 pathways while CMV activation may be influenced by mutations in HLA ,Toll-like receptors, immunoglobulin light chain antibodies, IFN lambda region as well as alternative transcripts of the CMV viral major immediate early genes.

Uveitis refers to the inflammation of the uvea, and early diagnosis is vital to minimising sight loss. This article provides a clinical overview of the condition and discusses the diagnosis and management of uveitis from the clinician's perspective, providing further insight into ongoing research. Rebecca Salter, mother of seven-year-old Riley, also shares her experience of helping her child to cope with uveitis.
